3. Set the 5790B for Input 2, Auto range, High resolution ON, GUARD ON.
4. Start with step 1 in Table 14. Set the DUT to 1 V for the main output and Product output setting V
and Hz in Table 14. Make a measurement with the 5790B. Record the measurement in the Product
Output column of Table 14.
5. Continue with the rest of the steps for this connection (steps 40 to 121). The main output to remain
set to 1 V for all steps.
6. With the entire table populated, evaluate each step for compliance to limits. If Guardbanding is to
be applied, create a table from the example in this manual where the acceptance limits are properly
modified by your Guardbanding method.
